I've flown the UA DEN-NRT 787 service three times since September in coach. I got decks of cards every time. I have not seen it on UA NRT-DEN or NH SJC-NRT (like NH is going to advertise for UA?). First couple times the decks of cards were kind of novel since I haven't seen any airline distribute poker cards in maybe two decades. I had to look twice to make sure they weren't complimentary cigarettes--that I haven't seen in a while! By the third flight, the novelty wore off with a small pile of unopened decks growing at home. I think I brought the unopened ones back and left them in the plane this last time.
How about the nifty UA logo packaged chopsticks and toothpicks?
